(Greek technetos `artificial') the first
artificially made element, symbol Tc, atomic
number 43. Originally produced by Perrier and
Segre 1937 by bombarding molybdenum with
deuterons or neutrons, it was later isolated
in large amounts from the fission products of
uranium. It is used as a hardener in steel
alloys.
